GLOBAL INDEXING WITHIN AN ENTERPRISE OBJECT STORE FILE SYSTEM
First Claim
1. A computer-implemented method for cache coherency, comprising:
- establishing one or more appliances, each defining a storage cluster;
establishing one or more tenants spanning across said one or more appliances, wherein an application stores objects in file systems associated with said appliances and said tenants;
establishing a global index (Gindex) including metadata relating to objects stored in association with said application, wherein each object is associated with a unique object identifier;
replicating said Gindex to plurality of data centers supporting said one or more tenants;
storing an original object at a first data center;
storing a cached copy of said object at a second data center;
aligning said cached copy of said object to said original object using metadata for said object from a local copy of said Gindex.

Abstract
A file system is disclosed that includes an application wide name space instantiated in a global index (Gindex) that is used for accessing objects related to an application. Using the Gindex, a method for cache coherency includes establishing one or more appliances, each defining a storage cluster; establishing one or more tenants spanning across appliances, wherein an application stores objects in file systems associated with the appliances and tenants; establishing a Gindex including metadata relating to objects stored in association with the application; replicating the Gindex to plurality of data centers supporting the tenants; storing an original object at a first data center; storing a cached copy of the object at a second data center; aligning the cached copy using metadata for the object from a local copy of the Gindex.

9. A non-transitory computer-readable storage medium having computer executable instructions for causing a computer system to perform a method, comprising:
-
sending a request for an object to a primary hub supporting a file system comprising an application wide object name space used for accessing objects of an application stored in physical file systems across one or more appliances, each defining a storage cluster, in association with a tenant logically spanning across said appliances; determining that said request failed; determining a secondary hub supporting said application wide object name space; and pushing said request to said secondary hub for processing. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A non-transitory computer-readable storage medium having computer executable instructions for causing a computer system to perform a method for accessing a file system, comprising:
-
establishing a tenant wide name space used for accessing objects of an application stored in physical file systems across one or more appliances, each defining a storage cluster, in association with a tenant logically spanning across said appliances; establishing a global index (Gindex) including metadata relating to objects stored in association with said application under said tenant, wherein metadata for each object includes a last modification time indicator, and wherein each object is associated with a unique object identifier; accessing objects stored in file systems associated with said tenant by corresponding object identifiers through said Gindex; receiving a rollback date/time; and restricting access to said objects stored in file systems associated with said tenant, such that access is provided to objects associated with a last modification time indicator that is older than said rollback date/time. - View Dependent Claims (17, 18, 19, 20)
